LG is integrating Apples AirPlay into its 2019 TVs along with Alexa. This means IOS device users will be able to launch their apps onto the TVs much like they do on Apple TV. This is the second major brand to announce such a partnership with Apple.
LG couched this with its announcement of TVs that roll in and out of a base that doubles as a sound bar. The screen literally rolls up like a shade over a window. When the screen is rolled the sound bar will still be operational.
The idea is space-saving and performance.
